Faye and Seb found Abi unconscious at home whilst caring for the twins and called an ambulance. Following that Abi was sent to rehab and the twins were taken into care.

Seb worked as a window cleaner with Tim Metcalfe after being sacked by Phelan and fell from a ladder shortly after rowing with Anna after believing she’d called Social Services.

He was rushed to hospital where Phelan dripped poison into his ear while he was unconscious, blaming Anna for his fall and telling Seb she wanted him dead.

While in hospital it was revealed that Seb had HIV.

He didn’t know but Abi thought he could be after an ex-girlfriend of Seb’s had the virus.

Seb and Faye took tests and Seb was devastated to find out his test was positive.

Seb played an important role in Phelan’s downfall after the serial killer confessed to him that he’d murdered Luke Britton and showed him the gun.

Terrified, Seb fled Weatherfield and turned to Nicola for help.

Seb and Gary tried to find the gun that killed Luke at the building site Phelan was working on but – when they were arrested for trespassing – the police uncovered the dead bodies of Vinny Ashford and Andy Carver.

Will Seb adopt Abi’s twins Lexi and Charlie?

Seb was horrified when Abi announced that she just couldn’t compete with the twins’ foster parents after finding out they were taking them to Lapland.

Abi mused that they gave Charlie and Lexi everything she couldn’t and that she was a better mum for letting them go.

Later Tracy Barlow found Abi collapsed on the street and called an ambulance.

She was rushed to hospital and when she was discharged her social worker told her that visits to the twins were cancelled indefinitely because of her drug relapse.

Abi told the social worker that she thought the twins would be better off with the family they are being fostered by.

Seb was furious at his mum for her choice and branded her pathetic before storming off.

In a rage Seb headed over to Tracy’s florist after finding out that she sabotaged Michelle Connor’s car and let Abi take the blame, which sent her on a downward spiral.

He was stopped by Abi who took the blame for him.

The Sun Online revealed that Seb would make a bid to adopt the twins.

A TV source revealed: “Abi is going to be dealt a new blow in the coming weeks.

"Seb launches a bid to become the legal guardian of his brother and sister.

"It means the kids would come and live with them and Seb would be responsible for them until he’s 18 when he can officially adopt them, so Abi can never get custody."

But Seb has to make a tough decision when he’s told he has to cut off contact with his mum if he has any hope of getting the kids.
